folio-classify-entity is a skill for Claude Code from alea-institute/folio-claude-plugin. It costs 104 tokens per session (461 once invoked), scanned A, a copy of folio-classify-entity, MIT.

A skill for classifying legal entities with the FOLIO ontology, a structured vocabulary for legal concepts. It checks both organization types and roles such as corporations, trusts, plaintiffs, and trustees.

In plain words
What is it for?
Finding FOLIO classifications, unique identifiers, definitions, translations, cross-references, and the relevant taxonomy branch.
Why use it?
It helps distinguish what an entity is from the legal role it plays, then returns the matching official concept and definition.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

folio-classify-entity scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Classify a legal entity against the FOLIO ontology's actors_players (roles and participants) and legal_entities (organization types) taxonomy branches.

Workflow

Given an entity name or description, follow these steps:

  1. Search for matches: Use folio:search_concepts with the entity name or description to find candidate entity types in FOLIO.

  2. Check both branches: Entities can appear in two branches:

    • Use folio:get_taxonomy_branch("actors_players") to check roles and participants (e.g., Plaintiff, Trustee, Shareholder)
    • Use folio:get_taxonomy_branch("legal_entities") to check organization types (e.g., Corporation, LLC, Trust)
  3. Get full details: Use folio:get_concept(iri) on the best match to retrieve the complete definition, translations, identifiers, and cross-references.

Output Format

Return the classification as:

  • FOLIO Label: The official FOLIO concept name
  • FOLIO IRI: The concept's unique identifier (e.g., https://folio.openlegalstandard.org/...)
  • Definition: The FOLIO definition of this entity type
  • Branch: actors_players (role/participant) or legal_entities (organization type)
  • Confidence: high / medium / low
  • Reasoning: Brief explanation of why this classification was chosen

If the entity could be classified in both branches (e.g., "Trustee" is both a role and relates to Trust as an entity type), note both classifications.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
